GPG + Gajim Portable?

I run Gajim 64 Portable on various Windows 10 machines. GPG plugin works only if GPG4WIN is installed. GPG4WIN allows to make a portable version, but I can't find the way to connect GPG4WIN Portable and Gajim Portable, please help. I've tried launching GPA or Cleopatra, but Gajim's GPG plugin still doesn't see any presence of GnuPG / GPG4WIN. Any help would be very much appreciated!
